They argue that Mosby and her husband, a city councilman who represents the epicenter of protests and rioting following Gray’s death, “seized political and personal gain” with charges intended to appease constituents and quell unrest. They also contend that the charging paperwork for the officers containserrors.

“Rarely in the history of any criminal case has a prosecutor so directly maintained so many conflicts of interest … and a prosecutor steadfastly refuses to recuse him or herself,” the attorneys wrote in the 23-page filing in Baltimore DistrictCourt.

The attorneys call the charges against the officers “extraordinary prosecutorial overreaching” at best. At worst, the charges “are something far morenefarious.”

The lawyers also claimed that Mosby’s charging paperwork contained errors and that she is too close to William H. Murphy Jr., an attorney representing the Gray family. (“[Murphy] supported Mosby’s campaign,” the Sun reports. “And, according to an email purportedly from Murphy and included in the filing, represented her in a matter before the Attorney Grievance Commission last year.”) Mosby has yet to respond to the filing, but based on what we’ve learned about her so far, it seems unlikely that she’ll back down without afight.
